RAILWAY sminerariel APPARATUS.

Application led February v20, 1905, Serial No.

To all whom it may concern: l

Be it known that I, WILLIAM MAooMBnn, a citizen of the United States,residing at Buffaldin the county of Erie and State 'of New York,have-invented a new and useful lailway SignalingApparatus, of which thefollowing is a specification.

invention relates to railway signaling apparatus, and more particularlyto signalm in'g apparatus oi the type actuated 'and governed byelectricenergy. The object of my invention is to positively move, lock,'give indication, unlock, return to noriiial,and give indication, by theapplicag tionv of electric energy from-a single battery. This inventionis, furthermore, an improvement upon and eral, basic invention disclosedin my applica- .tioii Serial No. 198,220, filed March 15, 1904, and itis also directly related to the invention disclosed in my applicationfiled February 20, 19.05, Serial No. 246,534.

A further object of my invention is to employ the general means of mysaid former invention, and to render positive every movement or actionof the signal, as above stated., and -to overcome the defects heretoforeeX- isting wherein a signal has reverse position frictionally, in whichthere. 33 has been no indication when the signal has gono to reverse,and in which the return ci the signal 'to normal has been whollydependent upon gravity.

Referring tothe drawing herewith, which asis .partly in elevation andpartly diagrainmatic, 1 is a four-pole solenoid for moving thesignal toreverse.

-2 is a similar solenoid for moving the signal to normal.'

3 is a signal blade, and 4 is a rod pivoted to the'signalblade shank. Ashort shaft 5 is slidably mounted in bearings whichare secured to thesignal post, and brackets 6, 6, rigidly secured to the shaft 5 areadjustably vv"secured over the shaft 4. The lower end of at; 'the shaft5 is yrigidly secured to the common armature of the solenoids 1 and ,2.Mounted upon the shaft ,5 is a plate 7 which is rectangular at its lowerend and beveled at an acute angle at its upper end. This plate 7 issecured to the shaft 5 and reciprolivoted at 9 upon the signal 3, whichis provided at its latch capable of engaging Cates with it.A post is alever arm lower end with a under the square end of the plate 7. lntegralwith the lever 8 is a lever 10, which Specification of Lattere Patent.

also swings upon the pivot 0 which pivot-ed at its upper end to a rodl5, which rod l5, at its free end, constitutes an armature for themagnet 12v and is capable of being drawn into said magnet 12 when it isenergized and the rod 15'is free to move. The arm 11 pivoted at 9, andalso integral with the arms 8 and 10, acts as a snap-switch, ashereafter morefully described, being permanently in electricalconnection with the contact plate 43, and alternately in electricalconnection with ,the contact plates 44 and 45.

The armature rod ofthe magnet 13 eX- tends through said magnet 13 and atits end adjacent to the arm 3 is provided with a slot 14, which takesover a pin in the arm 8. The slotted end 14 of the armature rod 36 ofthe magnet 13 has an extension 94 in the forniof an L, (the l. endextending directly backwardly so that it'does not show in the draw-ling). A plate 95 is rigidly secured to the shaft 5 and at right anglesto the plate 7. The plate 95 and thfy t.,-end 94 are so positioned that,when the armature of the inagnet 13 is in its normal, medial position,the L-end 04 will lie out of plane (to the left in the drawing) of theplate 05, and so that, when the magnet 13 is energized to draw the rod36 to its extreme (right hand) position, the L-end will lie in the planeof the plate 95. The upper end of said plate 95 stops a short distancebelow the L-end 94 when the signal is normal, and extends beyond thel...- end when the signal is at reverse. The 'purpose of thisarrangement is to delay indica-y tion until the signal is actually atnormal, asA vwill more clearly appear hereafterin tracing a movement.The outer end of armature rod 36 of the magnet 13 connects with springs99 which tend to hold the armature of the magnet 13 in the normalposition shown in the drawing, but which permit it to take the otherpositions at the proper time. Secured to the rod 36, but insulated fromit is a contact plate 37, which makes electrical connection when in itsnormal position with the contact piece 38, and which breaks suchconnection as soon as the magnet 13 moves the rod 36. 52 is a tonguenormally held out 12 and in electrical connection with contacts 39 and40, and when the magnet is energized breaking connection with thecontacts 39 and 40 and making connection with the contacts 53 and 54.

Mounted upon the armature ofthe magnet 13, but insulated romlit is aplate 49 which makes electrical connection with the contactsf50-and 51when the said armature is 5- normal, and which breaks such contact assoon 'as said armature is moved out'(to the ri ht) ofnormal.46isaplatesimilarlymounteg on said armature rod, capable of'makingelectrical connection with the contact 47 as soon as the said armatureismoved out of normal; and -48 is a plate similarly mounted and normallyin electrical connection with the plate 92', but capable of breaking4such connection and 'of making electrical connection with the contact90 when said armature is moved to its extreme position by the release ofthe L-end 94 from the plate 95 as hereafter fully described.

.17 and 18 are the brushes of the controller', 20 the brush I17 makingelectrical `connection with the contacts 19, 20, 21, and 22; and thebrush 18 being capable of making electrical connection with the contacts23, 24, 25, and

26. 25 27 are the indicating magnets; 16 are safety magnets; 28 is acut-out magnet, and 29 is a tongue governed by said cut-out magnet 28and carrying the'insulated plate. 30, which is normally in electricalconnection 3o with the contacts4 31 and 32; When the magnet 28 isenergized, the tongue 29 makes electricalfconnection with the contact33. v34 isa source 'of electric energy. The signalis shown in its normalor danger A35 position, and the position of the mechanism corresponds tothat position of the signal. I will now describe 'themovement of thesignal to reverse'andthe reverse indication." To

`produce this movement the'V brushes 1.7 and- 40 18 are moved with thecontroller so that the brush 17 bridges the contacts 2 0 'and 22, andthe brush '18 bridges the contacts 24' and 26.

This closesa circuit of the battery 34 includ-' ing the solenoid 1i, andthe magnet 1 2, so that .currentflows from battery 34 through wires 55,l56, 5 7, contact.31,'plate,30,'contact 32,'-

The current 'passing through the magnetg1-2- energizessaldmagnet' and-' tends to draw the 'armature rod 115 inwardly and at theSametime moves the armature'52 against the retractile spring -u iagainst the end of the magnet 12, 'breaking contact with- 39- and 40rim-making Contact with 53"' 6 5 and' 54,' The current from' batteryffinal movement ofthe controller giving mdioutsideof. all magnets on thecontroller so 4pending application Serial No. 198,220.' The so that` themagnet 12 should be denergized,

through safety magnets 16, has energized them and produced the releaseyof the con.- troller, as fully described in my'said pending applicationSerial No. 198,220. As soon as the rod 5 has carried vthe plate 4'7upwardly suiiiciently for the hook end of the arm 8 to engage over theend of the plate 7, the magnetic action ofthe magnet 12 upon the bar 1()Will overcome the tension of the spring 69 and cause the hook end of thearm 8 to snap to lace underneath the plate 7. This will loc the signalin the reverse position. The tongue 52 having moved to contact, as abovedescribed, the throw of-^the arm 8 into lock Will carry the arm 11downwardly and cause itly to make electrical connection between the late43 and the plate 45'.

The final movement of the controller will cause the brush 17 tobridge 100 contacts 2'1' and 22 instead of 20. and. 22 and will causethe'brush-"l-St bridge the contacts 25 and 26, so 'that `currentiWillflow JfromA battery 34,'through wires 55, 80, 'contact 21, brush 17,contact 22 and thence through the 105 path last above described, to thesignaland n ack` through the indicating wire to contact 26, brush 1 8,contact 25,and wires 81 and 77 back to battery. -Tln's carries thecurrent 110 that the slgnal-may be held at reverse inde- -pendently ofthe 4movement of any other 'I unit of the system, .and independently ofany.
